How do you identify ethonol resistant carb kits?
How do you identify ethanol-resistant carb rebuild kits? It's such a well-known issue, is there anyone actually selling kits that aren't? I see an Edlebrock kit from Summit Racing and a no-name kit from Dennis Carpenter that aren't identified as ethanol-resistant. Daytona Parts Company markets their kits as ethanol-resistant of course.

I believe all carb kits made these days are ethanol resistent. I haven't run into any that weren't. Just the old NOS kits that you need to beware of.

I had a failure of a ethanol resistant power valve in the late model Holley on my chevy truck took very old one out of flathead carb it went 10 years ---so being new and labeled ethanol resistant may not be any better than ordinary kit

Rubber line from fuel line to fuel pump cracked in only 2 years for me. I usually buy from C&G, cant say for sure on this item, usually C&G has been good to me. Where to buy a good one ?

Re: How do you identify ethonol resistant carb kits?
Do you recall if that power valve was a genuine Holley or maybe it was one of those generic 6.5" out of a rebuild kit? I had one of the latter fail in maybe a year without much actual use, not anything like a daily driver would see anyway. Its replacement seems to be OK. But .. keep an eye on plugs they sure foul up fast when the power valve goes.

It helps I think to buy parts and components and consumable items from actual dedicated carb guys versus rock bottom bargain basement no-name parts or kits from say, Am a Zon. Parts can look identical sometimes, but perform very differently. Those rubber vacuum caps on the parts rack - I've had the el-cheapos fail in less than 6 months, just fall apart. I don't know what it is they are leaving out of the "recipe" but anything for a buck I guess. Don't get me started on defective ignition condensers. If I ran a parts business, and couldn't stock dependable condensers, I'd just stop carrying them altogether. That ain't gonna break the bank. |
